Patent ES-295907-A1 (ES)
Title: Friction grip rope puller
IPC: F24D3/08
Filed: 1964-01-31
Abstract: Rope hauling apparatus comprising two frictional rope grips 14, 15 connected by links 16, 17 respectively to a rocking plate 24 on a shaft 25, has a substantially dust-proof casing 12, with an anchorage point 13, from which project an operating lever 18 connected by a link 22 to the rocking plate 24, and a knob 33 for selecting the direction of rope haulage. Slot engagement of the lever 18 on its pivot pin 19, in a disc 20, allows alternative lever ratios. The grips 14, 15 are reciprocated simultaneously in opposite senses so that. when one is gripping the rope and hauling it in one direction, the other is sliding over the rope on its return stroke. For haulage of the rope to the left, the links 16, 17 engage pins 30, 28 respectively on the grips 14, 15. To change the haulage direction, the knob 33 is raised to lift the links 16, 17 into engagement with pins 31, 29 or the grips 14, 15. The knob 33 can be turned to lock it in the raised position. In an alternative form (Figs. 2, 3, not shown) the link 16 is pivoted to a crank 43 rigid with a shaft 25 while the link 17, in the form of a belt-crank pivoted about a pin 57 on a link 56, is connected by a pin 55 to the grip 15 and by a link 52 to a crank 50 supported by shear pins 51 on a sleeve 48 rotatable about the shaft 25. Outside the casing 12, an operating lever 39 pivoted about a sleeve 41 keyed to the shaft 25 may be selectively connected to the sleeves 41 or 48 by a pawl 58 pivoted on the lever 39 and engageable with slots 59 or 60 in the sleeves 41 and 48 respectively. Thus the lever 39 may move either the grip 14 or the grip 15, the two grips being arranged to haul the rope in opposite directions. A spring 61, anchored at 62, acts on the pin 55 to urge the grips 15 and 14 (through links 17, 56) to engage the rope so that as the actuated grip is on its return stroke, the rope is held by the non-actuated grip. To release both grips a link 64, normally locked out of action, is moved left (Fig. 2) to act on the pin 55, through a link 65 to neutralize the action of the spring 61. An emergency operating lever, formed by the member 67 which normally is a carrying handle for the apparatus, has a forked end 71 engageable on an extension 66 of the part 54 of the grip 15 in which the pin 55 is pivoted. A lever 18 of the type shown in Fig. 1 may be provided to operate the grip 14.

Patent ES-344020-A1 (ES)
Title: Apparatus for returning a yarn end into an open end spinning machine
IPC: D01H4/50
Filed: 1967-08-03
Abstract: In an open end spinning machine wherein a yarn reserve is created to be fed back to the spinning chamber 32 in the event of the yarn becoming detached from the spinning chamber surface or on starting up spinning, the reserve is created by increasing the length of yarn path between the spinning chamber 32 and take up means 40 while spinning is in progress and at such a rate that the yarn count is not changed substantially. As shown in Fig. 3 the yarn is delivered through a tube 37 pivoted to the chamber delivery tube 36 and biassed away from the vertical by a spring 41. Normally the tension in yarn 38 balances the force of spring 41 and maintains tube 37 in the position shown in full lines. When the yarn tension drops tube 37 is drawn against a stop 42 and a switch 43 is closed. In consequence a solenoid 46 is operated to move an armature 47 which is linked to tube 37 and slides in a cylinder 48. Thus tube 37 is drawn into an upright position and the reserve yarn length created is sucked back into the collecting chamber by the suction applied to casing 31'. The motion of tube 37 to the vertical and its subsequent return to its normal position is controlled by a valve 50, a throttle 51 and an opening 49 in cylinder 48. In another embodiment (Fig. 2 not shown), the lengthened yarn path is obtained by passing the yarn about a pin displaced from the straight line path of the yarn the pin being retractable on yarn slackening. In Figs. 4 and 5 not shown the yarn passes along a series of tubes two of which are telescoped together on yarn slackening to produce a shorter path. In the embodiment of Fig. 5 the collecting chamber is stationary while a yarn gripping device associated with the delivery tube rotates. In Fig. 6 not shown, the yarn path is defined by an elastic tube which is normally stretched to provide a long yarn path but is released on yarn slackening to form a shortened path. In Fig. 7 not shown the path lengthening device consisting of a pivoted lever which deflects the yarn, is mounted between the doffing rollers and the spooling device and a further solenoid is provided to separate the doffing rollers on yarn slackening to allow the excess length of yarn to be drawn into the spinning chamber. An electrostatic spinning arrangement is shown in Fig. 8, the collecting chamber 84 being regatively charged with respect to the positively charged sliver feeding rollers 83. In addition to the solenoids operating the yarn path shortening lever 91 and opening doffing rollers 89 a further solenoid is operated on yarn breakage to pivot a suction tube 96 under chamber 84 so as to draw back the slack end of the yarn. A detailed description of the solenoid means for pivoting lever 91 is given.

Patent ES-347237-A1 (ES)
Title: A Method of Roasting Fine Granular Sulphide Material in Fluidized Bed Furnaces
IPC: C22B1/10
Filed: 1967-11-16
Abstract: A finely-divided sulphide-containing flotation concentrate, dried to a moisture content of 0-30% by volume is compressed by passing through a pair of rolls at a roll pressure above 0À5 tons/cm. roll length before passing to a fluidized-bed furnace, the resulting agglomeration being sufficient to prevent entrainment of material before completion of roasting. The rolls are preferably smooth and their speed of rotation may be varied. The agglomerated material may be stored prior to feeding to the furnace. Roll pressure may be 0À5-5 tons/cm. roll length. After rolling, oversized agglomerates may be broken up by a spiked roll. Sulphur may be incorporated as a binding agent by adding up to 5% by weight of finely ground sulphur which is heated to melting point during rolling, e.g. by injecting superheated steam or by electrothermal or induction heating, and then cooled in air. Alternatively, sulphates may be added in amount up to 10% by weight of concentrate by mixing with slightly moistened material the salts dissolve during rolling and then crystallize. Preferably iron, zinc and lead oxides from the furnace are mixed with sulphuric acid (which may be obtained from roaster gases) and the reaction between them is completed as the material undergoes compression. A preferred binding agent for pyrites concentrate is magnetic pyrites, Fe9S10, of particle size less than 50 Ám, added in amount up to 10% by weight before rolling. Other binding agents specified are sulphite lye, sodium sulphate, bentonite. Specifications 917,480 and 1,165,519 are referred to.

Title: Method for forming plastic tubing
IPC: B29C48/12
Filed: 1969-07-08
Abstract: Accurate sizing of longitudinally ribbed thermoplastics tubing is effected by passing ribbed extrudate 32 from extruder. 20 into a liquid-coolant chamber 40, maintaining a pressure differential between the interior of the extrudate and the liquid such as to expand the extrudate, and confining the extrudate by a series of encircling plates 55-66. These plates each have similar central orifices shaped such that spaces 250, Fig. 6, adjacent the peaks 201 of the ribs are greater than the spaces 252 adjacent valleys 225, thereby ensuring that peaks 201 cool at a higher rate than the valleys. Further plates 110-112, Fig. 1, support the set tube. The pressure differential is obtained by applying a vacuum to chamber 40 by means of an aspirator 81 and pump 83 and venting the interior of the extrudate to atmosphere via conduit 25. Liquid is supplied to chamber 40 by a pump 88 via a spray ring 90, discharge from the ring causing turbulence in the neighbourhood of plates 55-59. Chamber 40 is sealed at each end by glands 51, liquid being pumped through conduits 53 therein to effect the seals and provide lubrication for the extrudate. Further cooling chambers may be interposed between chamber 40 and haul-off mechanism 70. Thermoplastics mentioned are polyolefins, styrenes and acetates, the preferred material being low density polyethylene to which the parameters of the description refer. The tubing is particularly intended for use in making cigarette filter tips.
